DVCS connector with Git and workflow transitions

We've been using the DVCS connector with Git and GitHub at work for a while now, it allows us to tie our commits to the stories just fine but the feature we really want is the ability to transition the stories through the workflow. We use a custom workflow - no preconditions on the steps (there are some post conditions).

That categorically doesn't work, regardless of the format we go with. I've tried all the recommendations in the thread here. You can see I've commented there too but I'm no longer getting responses.
